- Background: This randomized trial examined whether lightweight (LW) polypropylene mesh (large pore size, partially absorbable) could have long-term benefits in reducing chronic pain and inflammation after inguinal hernia repair. Methods: Six hundred men with a primary unilateral inguinal hernia were randomized to Lichtenstein repair using a standard polypropylene mesh or a LW mesh in one of six centres. The patients were blinded to which mesh they received. Clinical examination was performed and a pain questionnaire completed 3 years after surgery. Results: Of the 590 men who had surgery, 243 (82.7 percent) of 294 in the standard mesh group and 251 (84.8 per cent) of 296 in the LW mesh group were examined in the clinic, a median of 37 (range 30-48) months after hernia repair. There were nine recurrent hernias in each group (3.7 per cent with standard mesh and 3.6 per cent with LW mesh). Patients who had LW mesh had less pain on examination, less pain on rising from lying to sitting, fewer miscellaneous groin problems and felt the mesh less often than patients with standard mesh. Conclusion: Use of LW mesh for Lichtenstein hernia repair did not affect recurrence rates, but improved some aspects of pain and discomfort 3 years after surgery.

- Objective: To explore the prevalence of and to identify possible risk factors for chronic pain after surgery for femoral hernia.Background: Chronic pain has become a very important outcome in quality assessment of inguinal hernia surgery. There are no studies on the risk for chronic pain after femoral hernia surgery. Methods: The Inguinal Pain Questionnaire was sent to 1967 patients who had had a repair for primary unilateral femoral hernia between January 1, 1997 and December 31, 2006. A follow-up period of at least 18 months was chosen. Answers from 1461 patients were matched with data recorded in the Swedish Hernia Register and analyzed.Results: Some degree of pain during the previous week was reported by 24.2% (354) of patients. Pain interfered with daily activities in 5.5% (81) of patients. Emergency surgery (OR = 0.54; 95% CI = 0.40-0.74) and longer time since surgery (OR = 0.93; 95% CI = 0.89-0.98 for each year added) were associated with lower risk for chronic postoperative pain, whereas a high level of preoperative pain was associated with a higher risk for chronic pain (OR = 1.17; 95% CI = 1.10-1.25). Surgical technique was not found to influence the risk for chronic pain in multivariate logistic regression analysis.Conclusions: Chronic postoperative pain is as important a complication after femoral hernia surgery as it is after inguinal hernia surgery. In contrast to inguinal hernia surgery, no risk factor related to surgical technique was found. Further investigations into the role of preoperative pain are necessary.

- OBJECTIVE: To describe the characteristics of femoral hernias and outcome of femoral repairs, with special emphasis on emergency operations. BACKGROUND: Femoral hernias account for 2% to 4% of all groin hernias. However, the lack of large-scale studies has made it impossible to draw conclusions regarding the best management of these hernias. METHODS: The study is based on patients 15 years or older who underwent groin hernia repair 1992 to 2006 at units participating in the Swedish Hernia Register. RESULTS: Three thousand nine hundred eighty femoral hernia repairs were registered, 1490 on men and 2490 on women: 1430 (35.9%) patients underwent emergency surgery compared with 4.9% of the 138,309 patients with inguinal hernias. Bowel resection was performed in 22.7% (325) of emergent femoral repairs and 5.4% (363) of emergent inguinal repairs. Women had a substantial over risk for undergoing emergency femoral surgery compared with men (40.6% vs. 28.1%). An emergency femoral hernia operation was associated with a 10-fold increased mortality risk, whereas the risk for an elective repair did not exceed that of the general population. In elective femoral hernias, laparoscopic (hazard ratio, 0.31; 95% confidence interval, 0.15-0.67) and open preperitoneal mesh (hazard ratio, 0.28; confidence interval, 0.12-0.65) techniques resulted in fewer re-operations than suture repairs. CONCLUSIONS: Femoral hernias are more common in women and lead to a substantial over risk for an emergency operation, and consequently, a higher rate of bowel resection and mortality. Femoral hernias should be operated with high priority to avoid incarceration and be repaired with a mesh.

Femoral and Inguinal Hernia : How to Minimize Adverse Outcomes Following Repair
- 2011

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Groin hernia is common, and each year 200 repairs per 100 000 adult inhabitants are performed in Sweden. Groin hernias are either inguinal or femoral (2-4%). Elective repair is not associated with an excess mortality, but adverse outcomes include recurrence and long-term pain. Emergency procedures have a 4% mortality rate with an increased risk for bowel resection and postoperative complications. The aim of this thesis was to identify risk factors for adverse outcomes and to propose measures to improve groin hernia treatment. Twenty-three per cent of female hernias were femoral. Thirty-six per cent of femoral hernias, and 5% of inguinal hernias, have emergency procedures. Females (OR 1.47) and patients above 65 years-of-age (OR 2.24) were at higher risk for emergency repair. Bowel resection was performed in 23% of emergency femoral repairs, and the 30-day mortality was 10 times that of an age- and gender-matched population. The majority of emergency patients were unaware of their hernia, and one third had previously had no groin symptoms. Femoral repairs were at larger risk for recurrence than inguinal repairs. The surgical techniques with least risk for recurrence were preperitoneal mesh repairs (open HR 0.28, and laparoscopic HR 0.31). Long-term pain was present in 24% of femoral hernia patients, of whom 5.5% described pain interfering with daily activities. The only factor predicting the risk for long-term pain was pain preoperatively. Pain decreased with time. In a randomized study on inguinal hernia, TEP resulted in less pain six weeks after surgery than Lichtenstein repair performed under local anesthesia (LLA). TEP patients were to a larger extent able to perform sporting activities. No difference was seen in intra-operative complications. Femoral hernias should be given high priority for repair and preperitoneal techniques should be used. Earlier diagnosis, in the elective setting, is probably difficult to attain. Heightened awareness in the emergency department is required. TEP is safe, and results in less pain than LLA six weeks after surgery. A widening of indications for TEP in primary inguinal hernia repair is justifiable.

- BACKGROUND: Femoral hernias are frequently operated on as an emergency. Emergency procedures for femoral hernia are associated with an almost tenfold increase in postoperative mortality, while no increase is seen for elective procedures, compared with a background population.OBJECTIVE: The aim of this study was to compare whether symptoms from femoral hernias and healthcare contacts prior to surgery differ between patients who have elective and patients who have emergency surgery.METHODS: A total of 1,967 individuals operated on for a femoral hernia over 1997-2006 were sent a questionnaire on symptoms experienced and contact with the healthcare system prior to surgery for their hernia. Answers were matched with data from the Swedish Hernia Register.RESULTS: A total of 1,441 (73.3%) patients responded. Awareness of their hernia prior to surgery was denied by 53.3% (231/433) of those who underwent an emergency procedure. Of the emergency operated patients, 31.3% (135/432) negated symptoms in the affected groin prior to surgery and 22.2% (96/432) had neither groin nor other symptoms. Elective patients had a considerably higher contact frequency with their general practitioner, as well as the surgical outpatient department, prior to surgery compared with patients undergoing emergency surgery (p < 0.001).CONCLUSIONS: Patients who have elective and patients who have emergency femoral hernia surgery differ in previous symptoms and healthcare contacts. Patients who need emergency surgery are often unaware of their hernia and frequently completely asymptomatic prior to incarceration. Early diagnosis and expedient surgery is warranted, but the lack of symptoms hinders earlier detection and intervention in most cases.

- Persistent pain is common after inguinal hernia repair. The methods of surgery and anesthesia influence the risk. Local anesthesia and laparoscopic procedures reduce the risk for postoperative pain in different time perspectives. The aim of this study was to compare open Lichtenstein repair under local anesthesia (LLA) with laparoscopic total extraperitoneal repair (TEP) with respect to postoperative pain. Between 2006 and 2010, a total of 389 men with a unilateral primary groin hernia were randomized, in an open-label study, to either TEP (n = 194) or LLA (n = 195). One patient in the TEP group and four in the LLA group were excluded due to protocol violation. Details about the procedure and patient and hernia characteristics were registered. Patients completed the Inguinal Pain Questionnaire (IPQ) 6 weeks after surgery. [The study is registered in ClinicalTrials.gov (No. NCT01020058)]. A total of 378 (98.4 %) patients completed the IPQ. One hundred forty-eight patients (39.1 %) reported some degree of pain, 22 of whom had pain that affected concentration during daily activities. Men in the TEP group had less risk for pain affecting daily activities (6/191 vs. 16/187; odds ratio [OR] 0.35; 95 % CI 0.13-0.91; p = 0.025). Pain prevented participation in sporting activities less frequently after TEP (4.2 vs. 15.5 %; OR 0.24; 95 % CI 0.09-0.56; p < 0.001). Twenty-nine patients (7.7 %) reported sick leave exceeding 1 week due to groin pain, with no difference between the treatment groups. Patients who underwent the laparoscopic TEP procedure suffered less pain 6 weeks after inguinal hernia repair than those who underwent LLA. Groin pain affected the LLA patients' ability to perform strenuous activities such as sports more than TEP patients.

- OBJECTIVE: The aim of the present study was to validate a Swedish translation of the Gastrointestinal Quality of Life Index (GIQLI) questionnaire in patients with gallstone disease. METHODS: Sensitivity to change, internal consistency, and test-retest stability were tested in 187 consecutive patients who underwent planned cholecystectomy. Construct validity was assessed by comparing the GIQLI score with the bodily pain scale of SF-36 and four single-item questions in a separate group of 104 patients. RESULTS: A significant increase in all five domains as well as in the overall GIQLI score 6 months after surgery (all P < 0.05) was seen. All five domains correlated significantly with other measures of gallstone-related symptoms except one single-item question. Intraclass correlations ranged from 0.62 to 0.87. Cronbach's alpha ranged from 0.77 to 0.89. CONCLUSION: The Swedish translation of GIQLI has a high validity and reliability for assessing the impact of gallstones on quality of life.
